15(S)-HEPE MaxSpec® Standard

15(S)-HEPE is a monohydroxy fatty acid synthesized from EPA by the action of 15-LO. The biosynthesis of 15-HEPE from EPA in guinea pig epidermal enzyme preparations has been documented. 15(S)-HEPE generated by soybean lipoxygenation of EPA inhibits RBL-1 cell 5-LO with an IC50 value of 28 µM. 15(S)-HEPE MaxSpec® standard is a quantitative grade standard of 15(S)-HEPE that has been prepared specifically for mass spectrometry and related applications where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This 15(S)-HEPE MaxSpec® standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product. Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.
